The Desco Ground Hub Continuous Monitor confirms the integrity of the resistance path from the common ground point to electrical ground. It is designed in accordance with ESD TR 12-01 to "monitoring equipment ground connections."

When the Ground Hub Continuous Monitor is plugged into the AC outlet, the green LED illuminates when both the outlet's wiring is correct and the path to equipment ground via the equipment grounding conductor is intact. The monitor provides 12 verified ground points when in PASS condition. The red LED illuminates when either the outlet's wiring is incorrect or the path to equipment ground is defective.

The outlet ground line is tested by measuring voltage between it and the neutral line. It is normal to have a few volts of AC induced on the neutral line. if the ground Hub Continuous Monitor measures only a few volts, the ground line is neutral impedance is low and the ground line would make a suitable ESD ground point. If the monitor measures more than just a few volts between ground and neutral, this indicates either that they are not referenced to each other or that the outlet and associated wiring should be checked for loose connection. In this case, the Ground Hub Continuous Monitor will sound a warning alarm and display a red FAIL indication and should not be used for an ESD grounding point until corrected.

“The grounding system must be verified periodically at the frequency established in a user defined ESD Control Program Plan.” [Grounding ANSI/ESD S6.1-2009 section 6.2 Verification Frequency]

“All of the grounding conductors from each of the ESD technical elements (excluding level 2 technical elements) used within an EPA shall be terminated at the same electrically equivalent point. The common point ground may be a terminal strip, bus bar or any other convenient configuration that is, within itself, electrically continuous to no greater than 1 ohm measured from point to point with an ohmmeter”. [Grounding ANSI/ESD S6.1-2009 section 5.2.1 Common Point Ground]

Constant Visual IndicatorLEDs provide a visual indication that outlet is properly wired for grounding purposes of an ESD Control Plan.

Visual and Audio Fault AlarmsAlarms activate instantly when a failure occurs, alerting user and supervisor of a problem.

Six Banana Jacks and Six Screws for #8 Ring TerminalsProvides numerous groundable points for wrist straps, mats, carts, tools, and other items.May also be connected to other grounding hubs. See Part# 09837
